自动遮罩¶

参考

模式:: 雕刻模式
工具:: 标题栏 ‣ 自动遮罩
快捷键:: Alt-A

这些属性会根据网格的几何特征自动对几何体进行遮罩。这是替代频繁手动遮罩的一种快捷方法。每次绘制新笔画或使用新工具时，这些遮罩都会被初始化。此外，它们绝不会作为叠加层显示出来。

请注意，这些属性适用于所有雕刻笔刷，但也可以在高级笔刷设置中针对每个笔刷进行单独配置。

可以按 Alt-A 键，通过饼菜单访问这些属性。

所有自动遮罩模式均可组合使用，这使得生成的自动遮罩更加精准。例如，可以对特定的面组进行自动遮罩，同时排除不连通拓扑和面组边界，并仅通过视图法向影响朝向视图方向的面。

拓扑

Only vertices that are topologically connected to where you started the stroke/tool on are affected. So loose geometry islands will be auto-masked.

Additionally for the Grab and Thumb brushes, anything that is not connected within the brush radius will be auto-masked. So even if geometry is connected somewhere, it is considered separate if the connection is not within the radius.

面组: Only vertices that are part of the same face set that you started the stroke/tool on are affected.

Tip

If no topology or face set is visible under the cursor at the start of the stroke, the previously auto-masked area will be targeted. This is especially useful with the "Projected" falloff shape in the Falloff Settings.

网格边界

Vertices that are part of open boundary edges are not affected. This also includes boundary edges to hidden faces.

传递步数: Increases the soft gradient towards the auto-masked boundary edges. Each step iterates the distance one edge further. This setting is used for both Mesh Boundary and Face Sets Boundary.
创建遮罩: This will execute the 网格边界遮罩 operator with the current auto-masking settings. This is very useful to visualize the current auto-mask, or to edit the mask further manually.

面组边界

Vertices that are part of a boundary between face sets are not affected. This also includes boundary edges to hidden faces. Propagation Steps are shared with Mesh Boundary auto-masking.

创建遮罩: This will execute the 面组边界遮罩 operator with the current auto-masking settings. This is very useful to visualize the current auto-mask, or to edit the mask further manually.

Cavity

Vertices that are the peaks of the surface curvature are not affected. While this auto-mask is primarily meant for painting, it can also be used for regular sculpting.

系数: The overall contrast of how strong the cavity is applied. The value of 0.5 is the default, but better results can also be achieved on 0.2 if a Custom Curve is used as well.
模糊: The number of times the cavity mask is blurred. A value of 0 will give the pure cavity auto-mask. Anything higher than 6 will likely have a less visible effect and decrease performance. Even though the value is capped to 10, it can be increased up to 25 if typing in the value.
自定义曲线: Use a custom curve to fine tweak the cavity auto-mask. This is very useful if only small crevices or flat surfaces should be affected. Or for example if the contrast should be increased/decreased in a specific way.
创建遮罩: This will execute the 腔体遮罩 operator with the current auto-masking settings. This is very useful to visualize the current auto-mask, or to edit the mask further manually.

腔体 (反相): This is the same as "Cavity", but inverted. This means the valleys/crevices of the surface curvature will not be affected. It cannot be used at the same time as Cavity and shares all of its settings. Enable this to quickly invert the cavity auto-mask.

视图法向

Only vertices with a Normal that face the viewer are affected. This is similar to the "Front Faces Only" toggle in the Brush Setting, to only affect visible geometry. The advantage of this auto-mask is that it has more options and works on sculpt mode as a whole.

遮挡: Change the View Normal behavior to only affect vertices that are not occluded by other faces. This setting is incompatible with the other Limit and Falloff sliders. It also causes a much slower performance.
限制: Determines the range of angles that will be affected. 90 degrees encompasses all that is visible.
衰减: Extends the angular range of the Limit slider with a soft falloff gradient. This falloff will visually extend the limit range further.

区域法向: Very similar to the View Normal, but uses the Normal of the surface that you started the stroke/tool on. This way any direction can be chosen for what vertices will be affected. It has the same Limit and Falloff sliders as the View Normal auto-mask.
